Abstract

NEW MATERIAL:A 4-p-alkylbenzoyloxypyridine oxide of formula I (R is 1W9C straight chain alkyl group).
EXAMPLE: 4-p-Methylbenzoyloxypyridine oxide of formula VI.
USE: Compounds for controlling the dielectric constant of nematic liquid crystals, used as photoelectric display elements, preferably in an amount of 5W30mol% based on the total mixture. The threshold voltage can be reduced sharply without changing the transition temperature.
PROCESS: A compound of formula II is reacted with a halogenating agent to give a compound of formula III (X is halogen), which is then reacted with a compound of formula V, obtained by oxidizing the compound of formula IV, to form the objective compound of formula I.
